Wineries Pump-Over Aeration

FOR MACRO AERATION:

Winemakers everywhere are discovering that pumping juice through a Mazzei® wine pump-over venturi injector during fermentation aspirates a substantial amount of air/oxygen into the liquid. Mazzei injectors are highly efficient, low cost devices for energizing fermentation. During the macro aeration process, the wine is pumped through a Mazzei injector which draws in and uniformal distributes oxygen into the juice. Trouble-free with no moving parts, Mazzei wine pump-over injectors deliver uniform distribution. They are simple-to-use, easy to clean, self-priming, and can run dry without problems. The superior mixing and contacting achieved is due to Mazzei’s patented technology.

BENEFITS OF MAZZEI WINE PUMP-OVER AERATION PROCESS:

Enhances Color and Character of the Wine

Supports Yeast Development and Viability

Reduces Sulfide Production

Excess Carbon Dioxide is Purged from the Top of the Tank

Can Be Used During Racking or Mixing

Installed at Top of Fermentation Tank or at Pump Discharge

Installed and Maintained Easily

Fining Agents and Other Wine Additives Can Be Introduced at the Suction Port of the Injector

Rate at Which Liquids Are Drawn Can Be Controlled with Addition of Metering Valve

FOR MIXING LIQUID ADDITIONS DURING RECIRCULATION:

The pump-over injector can also be used for liquid additions to tanks during recirculation. Simply connect an injector to the discharge side of a pump which is being used to recirculate the tank. Connect a suction hose from the injector’s suction port into the container of mixed addition (either fining agent, carbon, tannin, or anything liquid), and when the pump is running, the pump-over injector will draw the liquid into the tank at a rate you determine by the use of a throttling valve. No need for a stand alone dosing machine. No hauling buckets to the top of the tank—additions can be made safely from the cellar floor.

WINE PUMP-OVERS ARE AVAILABLE IN THE FOLLOWING MATERIALS:

Cast Stainless Steel: Made of CF3M cast stainless steel, our model 2081 venturi injector is a complementary product to model 316LSS, a machined product. The cast stainless steel product is a low cost equivalent which still offers vintners all of the high performance and quality they expect in a Mazzei product. With tri-clamp fittings at all openings, the 2081 can be installed and maintained easily. The cast stainless steel material resists corrosion and is easy to clean.

Natural PVDF or ECTFE: Mazzei also manufacturers a complete line of venturi injectors for the wine pump-over market that includes natural PVDF or ECTFE in various sizes and corresponding suction capabilities.
